Oil Radiator Module of Internal Combustion Engine

ABSTRACT

The present invention is an internal combustion engine oil dissipation module, which includes a head-set (a bolt-lock made by lathe or die-casting, with one side designed a fix-device and can be oil fill measurement meter and heat contact measure-head), a major heat-pipe (a heat-stream pipe, one side linked to the head-set, the other side join to the cooling fins that is listed plates in same interval) and an advanced transfer block (provide at least one expansion heat-pipe connect to the cooling fins). By this invention, major heat-pipe and expansion heat-pipe will conduct heat stream through lowest thermal resistance with the capillary and low boiling point vacuum vapor theory, then the temperature certainly drops down quickly by transfer heat to the big scale of cooling fins. It is absolutely machinery motion parts free, so it raises a lot of convenience.

Traditional engine oil cooler's structure is complicated, hard to install and cost a lot. Usually, they can not to drain out the remaining oil completely and do very easy to leak from the damage of collisions; these defects cause the at least on abnormal thermal dissipation.

Now, our new invention is to provide an innovational oil cooling module for the internal combustion engines. It includes:

One HEAD SET, this is a bolt part, made by lathe or die-casting and designed as a fixed section, which is functioned as measurement set for oil dipstick, in order to provide engine the oil nose hole joint for contact the heat source.

One HEAT PIPE, this is the vacuum pipe set to conduct the heat stream, with one side attaches at the Head-set, numbers of cooling fins that is to provide the major heat pipe to go through and conducted at the other side; the fins is a flake-like cluster jointed in same distance.

One HEAT TRANSFER BLOCK, this is set on the heat pipe and to conduct the heat stream onto it; there is at least one expansion heat pipe solder on the transfer block, which is a vacuum pipe device with one end run through and conducted by the plural dissipation fins.

One FRAME, covered in outside of the major heat pipe with one side connect to the head set and the other side to the heat transfer block, functioning to reinforce whole mechanical strength.

By this design, the whole module could minimize the counts of parts, sustain a simple structure and keep no machinery motion parts needed. This new module is rugged, reliable and quiet, no extra energy required and long life cycle. Using heat pipe as the transfer path for heat stream, this new design replaces the old structure using compressive liquid circulation. Experiment approves the drop down of engine temperature and also minimizes the machinery friction and oil waste. Furthermore, it could reduce air pollution, promote the Eco-life effectiveness and significantly raise the application convenience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To easily understanding the features, content and strength of this invention, we attached the drawings and tables of implement method to express the details on the followed pages; all the graphics used are for showing and assisting the idea of this new invention maybe in different scale and layout from real product in the future. So we expressed in advance, it wouldn't be limited to the coverage of this invention

Please refer to the FIGS. 1, 2 and 3, those are the 3-dimensional decomposition, assembly and profile drawings. This innovated radiator module includes one head-set 21, one major heat pipe 22, plural cooling fans 23.

As described earlier, the head-set (HEAD) may be a bold made by lathe or die-casting; the metal material could be copper, aluminum, stainless or other alloy combined but no limitation to this invention. In the other words, any method constructed and any material (metal or non-metal) used is adoptable.

And, the head-set 21 has one side designed for the fixed device joint 212 and for the measure-head 211 of oil dipstick to contact heat source (e.g. the oil 6 of FIG. 7). The measure head as a combination device could be made by copper, aluminum, stainless or any alloy but not limited to other material can conduct the heat stream. For fixing engine at its oil fill hole-thread 51, the head-set 21 use the fix-device 212 with a central through holes 210 and 2120; its material can be metal or non-metal but no limited to those can stand the high temperature. Also, the die-casting or compressed parts can be nickel or tin plating in color processing, as long as in good duration of welding, corrosion and weather and in nice shape.

The major heat-pipe 22 is a closed vacuum pipe device to conduct heat stream with low thermal resistance character. This heat-pipe can be made by copper, aluminum, stainless or other alloy but not to limit for this invention; any heat conduction material is acceptable.

The heat-pipe 22 has one side connected to the through-holes 210 & 2120 of head-set 21 and its fixing device 212. Also, heat-pipe connects to the measure-head 211 as fill-hole which serves measurement dipstick; its fixing method can be screw (FIG. 8) or QR-type (FIG. 9). The heat-pipe 22 and the head-set 21, plus fix-device 212, could be made by soldering or gluing process. This exemplar module is made by tin-soldering into a fit-module.

The vacuumed major heat-pipe 22 contains copper mash, copper ball and water (or other vaporized materials); we use the inverse theory between vacuum and boiling point. It is when the heat-pipe contact the heat source, the water inside has very low boiling point starts produce vapor to carry the heat-stream to other side of heat-pipe. After the vapor cooled down and come back to lower side of heat-pipe, with mash inside near to the engine measure-head 211, the water effected by capillary theory of mash soon bring the vapor again to the other side of heat-pipe 22. Therefore, in circulation, the vapor carries heat-stream to other side of heat-pipe 22, gets cooled and then become water flow back to lower position side of heat-pipe.

The plural dissipation fins 23 (FIN) is to conduct the heat-pipe 22, made by heat transfer material, providing great area to contact the air and fan out the heat to atmosphere, thus to meet the lower effect of heat-stream. These fins 23 are assembly buckle plates in same distance.

Please refer to FIG. 8 for the QR-type (Quick Release type) example schematic. In this invention, the heat-pipe 22 connects to the head-set 21 at fixing side and run through its through holes 210 and 2120.

The head-set 21 is made by metal material, tin-soldered with the heat-pipe 22; while the heat-pipe can be selected to use metal or non-metal materials, it could use the glue process to join with the head-set 21, but not limited. Any kind of connection method is to join the head-set 21 and its fix-device 212 that fixes the engine 5 at the oil fill hole 51 (e.g. FIG. 7). The fix-device has insertion lining 2121 made by one of soft rubber or silicon rubber material into one set, but not limited to this invention; Any material has some bulges is acceptable, and it can seal up between the head-set 21 with fix-device 212 and engine 5 with fill-hole 51. The head-set has no screw teeth and must be sealed with the soft rubber or silicon lining 2121. The removable lining provides the engine 5 compress component and the head-set 21 anti-leaking function. If the head-set 21 and its fix-device 212 are metal, its material can select from copper, aluminum, stainless and any alloy but no limitation to this invention.

Please refer to the FIG. 9, the screw-locking method example of this invention. The major heat-pipe 22 runs through head-set 21 at hole 210 and fix-device 212 at hole 2120; the fixing device 212 has screw is designed for fix and seal purpose. The locating ring 214 is used for head-set 21 and fix-device 212 to join the major heat-pipe 22. And, the fix-device hole 2120 has a semi-buried type oil-seal 213.

It is the O-ring 2131 which has half part fixed into the fix-device hole 2120 and inside notch 2130. This O-ring 2131 has the other half part to be compressed the heat-pipe 22, thus to prevent the leaking.

Because the heat-pipe 22 and head-set 21 fix-device 212 are removable, it can be compressed with the oil fill-hole 51 of the engine 5.

If the head-set 21 and the fix-device 212 is made of metal, it could produced by lathe or die-casting, but not limited to this invention; any material is temperature durable all adoptable. Also, nickel and tin plating like colored processing, very nice in good shape, is good to for the character in temperature, corrosion and weather duration.

Please refer to FIGS. 4, 5 and 6: the 3-dimension exploded drawing, assembly drawing and profile drawing of this invention showing the internal combustion engine's dissipation module in very well implementation method, as its structure is pretty much the same example structure on FIGS. 1, 2 and 3; the only difference is at major heat-pipe 22 has advanced set lat least 2 (plural) hole-drilled cooling blocks 3 (TRANSFER BLOCK). These transfer blocks 3 can be made by compressing, die-casting or other process. One of its hole 30 is covered to major heat-pipe 22; its purpose is to absorb the heat and transfer and same as other holes to provide at least one Expansion Heat-pipe 4 connect together.

The Expansion Heat-piping 4 has same function and structure as major heat-pipe 22, with mash and water inside the sealed vacuum pipe, similarly, its one side will rung through the dissipation Fins 23 and being jointed and conducted.

By this design, the major heat-pipe will transfer heat-stream firstly to the transfer block 3, and then connect to at least one expansion heat-pipe 4. Consequently, using the capillary theory of the mash and water vaporized to delivery heat stream to the other side of heat-pipe which connected great area of cooling fins 23 to fan-out the heat source into the atmosphere, in order to drop down the temperature quickly as required.

Also, this implement example can reaches a two sided expansion heat-pipe 4; with major heat-pipe 22, the heat stream can be drain out quick and balance by soldering process jointed tightly with cooling fins 23.

By this design, heat dissipation capability is doubled.

And, the example implementation is made by tin-soldered, but no limitation to other process; Also the parts processed by compressed and die-casting can choose nickel or tin plating and color processing for better character in corrosion, weather and good looking features.

Please refer to the FIG. 10: the other exemplar drawing of implementation, it's about the same as FIGS. 4, 5 and 6. The only difference is the FRAME, made by aluminum die-casting, located among major heat-pipe 22, head-set 21 and the transfer block. Its function is to reinforce the mechanical strength; it can be metal parts by die-casting or by compress-process to made head-set 21 and transfer block 3 all together as one set. This manufacturing method will minimize the component number and raise the metal strength to against the vibration damage from automobile motion.

The dissipation Fins 23 of this invention can be placed at any position and also be mounted at the air-inlet of cooling fan 52 of the engine 5, in order to make force-cooling methodology. Nevertheless, this invention is using the capillary and vacuum vapor theory inside the heat-pipe 22, almost the jet sonic speed, to fan out the heat stream through major heat-pipe 22 into the big sized cooling fins 23 at the other side. Then, the heat stream will quickly be dissipated to atmosphere by the cooling fins 23, thus temperature drop down soon.

This invention module has less components and simple structure without any machinery motion parts. It reduces a lot of cost, has good effectiveness and longer life cycle. And, it certainly lower the working temperature of engine 5, reduce the friction & oil waste and air pollution. Eventually, this invention will provide the benefit for government around the world minimize the carbon-rate and reach the Eco-earth earlier.

By the replacement of old liquid compress-circulation theory, this new innovation brings the Gain-effects as following:

1. Using head-set (HEAD) 21, major heat-pipe 22, buckled cooling fins 23 and transfer block 3 to build a powerful dissipation capability and combine the function for oil measurement dipstick become a machinery motionless oil cooling device.
